' mrnovnmnn' m'THILL-coUPLmes;

The, Schedule referred to in these Letters Patent making part of thesame I, GEOR E WLIuIeE, of Adrian, in, tl1e county of Leuawee, andState-of Michigan, havefiuvented cer-' tain Improvement-sinThin-Couplings, of which the following is a specification.

The nature of imyinveutiou consists in the use of I a hooked draw-jackfor thill coupling, with a lidhung upon .a ;pin directly over the centerof the eye, and

held down by a bolt and nut.

Iu thedr'awings v r g 1 Figure 1 is a side elevation of my improvedcoupling in complete workiugorder; I

'Figure 2 is aview' of the upperside of the same. A isthe hinged lid,turning upon'the pivot tin the end of thehook B; w 1 E is the eye, and VI bushing; I 'm the bolt; and n, theuut; S is the yoke, bent around the'axle-tree; and V 15,-the Washer, to holditiu its place. The hookorrelip B of this coupling is supported on thefrontpfa ce of the usualaxle-yoke, and consists of a bracket or hook, ext-ending forward fromthe' axleyoke, and turning up over the opening or depression forthe'thill-iron, to thoocenter of said opening or depression'.

The lid or cap A is hinged to the extremity of said hook or bracket B,above the center of saiddepres-. sion, for the purpose of holding downthe thill-iron E- and the rubber ,or leather bushing oin its place,

and is held down and secured in its place by the screw-bolt m, and nutn. y

The rubber or leather bushing is used in the same manner as formerly,there being nothing new claimed about it..

As the forward wheels of the vehicle fi-equently de-,

scend into low places, and the horse at the same time risesupon anelevation, thetdraft is instantlythrown to nearly a right angle with acentral line of the book 13, as shown bythe dotted lines in fig. 1.

To increase the strength of the coupling and avoid breakages in such acase, the whole isso constructed that the draft shall'come entirely andat all times on the hook, and that in shifting the thill irou E it shallbe raisednpward and shoved backward.

'Inthis way all strain is taken 05 (sf-the hinge-cap A, a fact that addsmaterially tothe value of' my improvement over others in use.

' Claim. \Vhat I'clair'n as my invention is The bracket orhook B, incombination with the -oap A, hinged-directly over the eye, and fastenedwith the screw-bolt m and out n, that the draft shall come on said hook,for the purposes and in the manner set ouoee'a w, aron.

' forth and described.
